I was looking for a barrel for a Ruger MkII. Does anyone know the thread size and if so know of another rifle that shares the same thread? How about a website that list barrel thread sizes?

16 V TPI .998". This is from de Hass "Bolt Action Rifles"

Thanks. So the Ruger is 16V & .998" and the Winchester is 16V & 1.00"

Dehaas took measurments from samples. In reality, both the Ruger and the Winchester are 1"x16tpi (nominal size). Regards, Bill.
